ROLLER-SKATE.

SPECIFICATION forming part Of Letters Patent N0. 674,727, dated May 21, 1901.

Application filed November 21, 1900. Serial No. 37,269. (No model.)

To (LZZ- whom, it may concern.-

Be it known that I, THOMAS WALLAoE BRYANT, ofTorrington, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Trucks for Roller-Skates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in trucks for roller-skates, the object of the invention being to so construct a truck that all strain shall be brought longitudinally of the same, avoiding the use of angular arms for securing the truck to the foot-plate, and at the same time to so construct the truck that it shall have a wide and extended bearing against the bottom face of the foot plate, whereby lateral displacement will be effectually prevented.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view illustrating my invention and its application to the foot-plate of a skate. Fig. 2 is a perspective View of one of the truckarms. Figs. 3, 4, and 5 are views in crosssection, showing modifications of the truckarm.

My improved arm consists of a plate 1, preferably of sheet metal and may be conveniently made somewhat tapering. The body of the truck-arm is made with a lateral bulge or corrugation 2, extending from the top edge of the arm to a point removed a short distance from the lower end thereof. This bulge serves to strengthen the arm; but it also performs the more important function of affording an extensive bearing at 3, laterally of the arm, against the bottom face of the foot-plate 5. At each side of the bulge 2 the truck-arm is provided on its top edge with lugs 4, which are passed through slots in the foot-plate 5, and their free ends are upset upon the top face of said foot-plate. When the arm is made of sheet metal, it can be stamped and cut from a strip of sheet metal at a single operation, and at the same time a bearing 6 will be formed at the lower end of the arm for the axle of the skate-wheel. This bearing is made elongated by pressing the metal outwardly when the arm is stamped to form a short integral tube or sleeve, as shown at 7.

In Figs. 1 and 2 a single bulge or corrugation 2 is shown as marking the segment of a circle in cross-section; but several corrugations could be zigzag, after the manner shown in Figs. 3 and 4, or the cross-section of the bulged portion of the arm might'be made serpentine, as shown in Fig. 5.

My improvements are very simple in construction, can be stamped at a single operation from a single sheet of steel, and are effectual in all respects in the performance of their functions.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A roller-skate truclg having depending supportingarms, each of which is made of a flat metallic plate having a hearing at its upper end against the foot-plate and provided at its upper end with projections for rivetingit to the foot-plate, and also provided with one or more vertical corrugations extending to its upper edge to afford the latter an extended lateral bearing on the under side of the foot-plate.

2. A truck-arm for a skate made of a single piece of metal adapted to bear against the under face of a foot-plate and having an intermediate bulge constituting a lateral protuberance to form an extended bearing erally from the arm and against the footplate, and lugs projecting upwardly from the top edge of the arm, at respective sides of said lateral protuberance for riveting the arm to the foot-plate.

3. A truck-arm made of a single piece of sheet metal having an intermediate lateral protuberance to form an extended bearing against a foot-plate, means for securing the upper edge of the arm to a foot-plate at each side of said protuberance, and a laterallyprojecting integral bearing tube or sleeve at the lower end of said arm.

4. A roller-skate truck comprising two independent separated, depending arms, each consisting of a metallic plate provided on its" to afford the latter an extended lateral bear- 1 ing on the under side of the foot-plate, said 1 plate also having a laterally bulged or corrugated intermediate portion extending to the upper edge thereof to form a lateral hear:

ing against the foot-plate and terminating at its lower end above said integral tube or sleeve.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

THOMAS WALLACE BRYANT.
